Engine shake

[Beaver77]

On my swift 44 the port engine has a little visible shake between 800-1400rpm then smooths out above that….that engine also usually has one to two lbs more boost than the starboard for a given rpm which I have attributed to the props not balanced which I intended to fix….the engine shake I can also see a slight wobble of the shaft where it goes into the seal at that rpm, I guess it is slightly out of alignment or maybe related to the prop? Only had the boat 6 months but on the survey the props looked fine thanks

The easiest thing to check is engine alignment. Pretty easy thing to do.
